Installation Notes
-
Bending Radius: Strictly follow 6×OD (≤16mm²) / 8×OD (≥25mm²) rules.
-
Pulling Tension: Use rollers – max 50N/mm² conductor stress.
-
Corrosion: For direct burial, ensure soil pH 5.5–9.0.
-
Fire Zones: Mandatory in EN 50575 Euroclass B2ca-s1,d1,a1 installations.
-
Compliance: Install per IEC 60364 & BS 7671 regulations.
⚠️ Critical: Armor must be grounded at both ends per IEC 60364-4-41.
